Yes, six days actually, with a day of rest following. I can't tell you for sure how long a "day" was in Genesis, but I have read commentaries that state that the Greek word used in the passage is meant to convey a 24-hour day. (There are other verses in the Bible where the word signifying "day" means a different length of time.) I certainly believe that God is able to create whatever he wants, instantly if he so chooses. We cannot understand the mysteries of God, which is where faith comes in.
...with all of the species and humans as we know them? dinosaurs existed millions of years before humans, didn't they?
God created a mature man and woman...and mature animals (not infants). It seems reasonable that he would therefore create a mature earth, with it's oil reserves and other resources in place, and even some proof of continents moving great distances. No one knows for sure when dinosaurs actually exisited (dating by strata or "carbon dating" is problematic). There are some verses in the Bible (Job) which describe creatures that we would call "dinosaurs", they apparently existed before the great flood. Perhaps the different world that emerged post-flood led to their extinction ?
Not to be disruptive here, but Genesis was written in Hebrew by a Jew named Moses.
Shalom.
